Processing Backorders (SAP Library - SAP Advanced Planner and Optimizer (SAP APO))

Processing Backorders

Purpose

Backorder processing can be planned interactively or in the background (regularly, if necessary).

after a planning run in PP/DS, in Supply Network Planning or after changes in the location-specific product master data for ATP
after a changed availability situation
after the arrival of orders that have priority

Backorder processing should be used in APO for APO relevant products.

Prerequisites

You made the settings for backorder processing. In Customizing for the Advanced Planner and Optimizer (APO) select Global ATP ® Tools.

When overriding the results of the availability check in interactive backorder processing you must be in a position to guarantee coverage of a receipt element to be procured.

Process

You carry out, for example, a product availability check using the checking horizon (replenishment lead time).

There is a shortage because the checking horizon has expired and no new receipt elements are found.

You execute batch backorder processing and reset the confirmation of the order items so that other (as yet unconfirmed) order items can be confirmed.

The update takes place in the connected OLTP system.

If a document (such as a sales order) was changed manually during backorder processing or if items were already delivered, the backorder processing results are not adopted.

In order that this restricted results transfer can function, the change management (switched on as standard for documents) must be activated in R/3. For more information see Change Documents in ABAP Workbench (BC-DWB).
